Government entities have had to make some tough choices regarding using their finite budgets for acquiring traditional orthophotography and oblique aerial imagery.
OrthoPhoto Limitations
Orthophotography is user friendly because it can be loaded into a GIS/Mapping system where the location and distances can be easily determined as long as the measurements are made at ground level. But because traditional orthophotography provides only a single top-down view, it cannot be used to see or measure the sides of buildings clearly visible in oblique pictures.
Oblique Aerial and Orthos from the Same Flight
The market is quickly demanding the contextual value of oblique views with the location accuracy they are accustomed to with orthophotography. As a pioneer in the delivery of spatially accurate imagery, expect
GEOSPAN
to fulfill this demand at an affordable price.
GEOSPAN
’s collection technology supports offering both types of imagery with one mission.
GEOVISTA®
camera systems for light aircraft contain five digital cameras pointing forward, back, right, left and down. Imagery from the nadir camera can be ortho-rectified to create a seamless result meeting 1” – 50’ map accuracy with 4” pixels. In a single flight, enough imagery is captured to offer 360° viewing of 12 to 24 different oblique views of every location with a pixel resolution of 3” to 6” providing a tremendous amount of visual detail.
